Brettski, nice work as usual. How did you calculate the size of the furnace and A/C unit? I've been looking on-line for a heat loss calculator to properly size heating and A/C systems and I haven't found any that I can use. I will be replacing the furnace and A/C system in the house shortly and want to make sure it's properly sized. I think the one that is in here now is undersized on both the heat and cooling ends.
